The roller is an important piece of equipment in the process of a new energy lithium battery. Through the roll pressure, the battery material will be compacted to obtain the prototype of the pole piece.   Roll surface cleaning is very important to ensure production yield!   The traditional way of cleaning rolls, using manual wiping rolls, there are many disadvantages. The use of lasers to complete the rolls of high-quality cleaning is imperative.   In the new energy lithium battery manufacturing process, pressing the battery electrode roller is one of the key steps.   Through roller pressing, the active material on the pole piece (usually powdered positive and negative materials) is compacted to obtain the desired shape and thickness of the pole piece, and keep the surface smooth and flat. The compaction density and thickness of the pole piece, as well as the bonding strength of the active material to the collector foil, have a direct and important impact on the phys...

Photovoltaic power generation is based on the principle of photovoltaic effect and utilizes solar cells to convert sunlight energy directly into electricity. Chalcogenide material is a semiconductor material with a special crystal structure, which is widely used in solar cells. In the preparation process of chalcogenide solar cells, edge clearing is an important step, which helps to remove the excess chalcogenide material at the edge of the cell and avoid the influence of the edge effect on the cell performance. By precisely controlling the edge-clearing process, the structure of the cell can be optimized and the non-radiative composite can be reduced, thus improving the photoelectric conversion efficiency and long-term stability of the cell. In addition, edge clearing helps to improve the appearance quality and overall performance of the cell, making it more reliable and efficient in practical applications. This article mainly provides solutions for the application of Raycus 's fl...

In today's rapidly changing laser technology, solid-state lasers and fiber lasers as the two mainstream laser products, each in industrial production, scientific research, military applications and other areas to show the unique charm and advantages. First, the technical principle and performance differences 1.  Gain medium   Fiber laser (Fiber Laser) is used as a rare earth element doped glass fiber gain medium. Under the action of pump light, high power density is formed in the fiber, resulting in the reversal of the number of particles in the laser energy level, and generate laser oscillations through the positive feedback loop of the resonant cavity. Fiber lasers are compact, do not require complex cooling systems, and the flexibility of the fiber makes it more advantageous in multi-dimensional spatial processing applications.   At the heart of a fiber laser is the optical fiber, a flexible, hair-thin glass or plastic filament known for its ability to direct light ove...

In recent years, with the development of laser processing technology and the intensification of homogeneous competition in the laser industry, miniaturization has increasingly become one of the important trends in the development of fiber lasers. Miniaturization not only means a more compact structure and lighter weight, but also represents a higher degree of integration, which can more easily realize the automation and intelligence of industrial production, which is crucial for improving production efficiency, reducing operating costs, and enhancing market competitiveness. At the same time, the miniaturization trend of fiber lasers is also accompanied by reduced energy consumption and heat, which perfectly fits the current global green and environmental protection development concept. Multi-scenario application of miniaturized cleaning lasers Miniaturized cleaning lasers are widely used in many scenarios, such as rust removal, paint removal, oil removal, precision manufacturing, and c...

With the continuous improvement of the packaging requirements of artificial intelligence chips, many head enterprises are carrying out advanced packaging technology updates and iterations, in the packaging material innovation, a glass substrate is currently the most popular. Glass material's high stability, low coefficient of thermal expansion, high-frequency electrical characteristics, low cost, superior airtightness and corrosion resistance, etc., resulting in it is expected to replace the silicon-based rotary plate packaging materials. Moreover, the glass substrate has been successfully applied to Micro LED, MEMS, AiP, IPD, and other fields. One of the core processes of the glass substrate is the preparation of TGV (Through glass Via), TGV technology needs to take into account the cost, speed, and quality requirements. One of the main constraints to the development of glass through-hole technology is the TGV hole-forming technology, which needs to meet a series of requirements s...
